HI Team,

What's below VOD value? I check the datasheet in DS90ub954 it has a |VOD| from 140-270mV, is this value correct? There is also a spec named |deltaVOD|, what's this used for?

And we only specify jitter requirement for the DS90UB954, how about the requirement for the eye height?

Thanks

Hi Ted,

Can I ask why you are interested in this? Did you want to qualify the link? If so, we recommend that you use the MAP tool in our ALP GUI instead.

Thanks,
Sally

HI Sally,

My customer conduct the eye test and they're wondering if there is any requirement for the eye height.

There is clear requirement for the eye width in the datasheet.

Could you pls help?

Thanks

Hi Ted,

The eye height is specified in the EC tables of the datasheet, please check again. The value is right next to the eye width.

Please refer to this thread as well:
